SPARK PLUG: DENSO IW27 OR IW29 (IF PERMITTED) OR ROTAX GR8DI**

**NOTE ON PLUGS: Colder plugs (31/34) always look slightly better on the dyno, but they don't make a difference on track. Trust us on this. We have been tuning Rotax motors very successfully for a long time, and this has always been the case. Cold plugs tend to foul on the grid and they don't last nearly as long as 27s or 29s. If you insist on using a 31 or 34 plug, replace it after every competitive session.

Major upgrade to the shop with this proper engine stand, courtesy of Kartune Motorsport in the UK. When it comes to #karting the Brits do it right. Thanks to @aventus_power for the tip. . . #iameusa #x30 #enginetuning #UK #kartracing
Racing finally returned to the Northeast, and what a way to start with clean sweeps in X30 Senior and Junior, and great results all around from all of our drivers. The countless hours at the bench and on the dyno during our downtime certainly paid of

A nice batch of @rotaxkarting work got me thinking back to happier times, like P11 at the 2017 Rotax Worlds in Portugal with @aidan.fox.44. Year 2017 > 2020 might be the understatement of the century. I love the Rotax format and have always enjoye

A little known and underreported symptom of the corona virus is #waft. With no racing, all there is to do is get prepared. X30s, KAs, Mini Swifts, and even a Rotax Mini Max MY20 conversion...our drivers will be on fresh, fast engines when racing resu
@superkartsusa #supernats23 P25 of 78 entries Decent result after the 101% track condition rule killed our qualifying and we had to start at the back of every heat. @kartdavid @freemuk @tillotson_racing @tillettracingseats @otkkartusa #expritkar

Back @ovrp1 this weekend, our X30 drivers set the pace but had no luck in the races. In @rotaxkarting Mini Max Aidan Lourenco drove from last to third after a dropped chain in the prefinal, while @vivekracing continued his domination of the field. Ke
Good day @ovrp1, proud of all of our drivers. #X30 power was on point with pole in both Jr and Sr, race win in Jr, and only last lap contact preventing P1 in Sr. Debut of the new @kartdavid engine decals was a hit! Special thanks to @brandonjarsocrak
